The iPhone Thread

This is a discussion on The iPhone Thread within Gadgets, Computers & Software, part of the Shifting gears category; I have an airtel sim and I'm using the iPhone 3g with 4.0 jailbroken + unlocked.
I just restored my ...

The problem I am looking at is how do I jailbreak my 3.1.3 iphone 3gs using Spirit? Spirit says that I need an activated iphone to jailbreak. Can it be done using an official sim inside? If yes then I think I should start looking for an official AT&T sim to unlock.

Man I am so so stuck. The dev team isnt of much help either.

Even i,m stuck with the same problem. You need a AT&T active SIM card to activate your phone & later you can jailbreak & unlock it on whichever OS you want . In my case i found a shop nearby who got this SIM so mostly ill get it done from him. Hope it helps.

You do not necessarily need an AT&T sim. It depends on what is the "official carrier" of your iphone. This depends on your model number thats either present on your iPhone Box, or download the latest version of TinyUmbrella from their website and connect your 3GS on it.. it will say whats your exact model number.
Once you get that, you can google to find whats the official carrier for that model. There are a couple of forums that has an entire list of them along with model codes.
I found out mine corresponds to O2 from UK or Ireland... I ordered a sim online and will get it in a few days; will let you know if it works.

BTW, i tried AT&T sim too thinking its going to magically work... but nope!! No Luck.

I came to know this recently from some help on the dev team website. Here are some more useful info--

- The unlock released for 3.1.3 and 4.0 are only for previously jailbroken and activated phones. They always forget to mention "activated" because its assumed that you had it activated either through itunes or custom firmware for it to run and jailbreak. And activations without a custom firmware can only happen if you are having an official sim and that is what I am going to find out soon. All fingers crossed!
- Custom firmwares will not work if your phone wasn't jailbroken or hactivated at that time of restore.

There is hope for people on the old bootroom though. Easiest way to find this out is
- Take out the Sim Tray and the sim
- You will find tiny numbers etched on the sim tray. One is the Serial num and the other is the IMEI number I think
- Your 3 digit should be a 9 and the 4th and 5th digit should be less than 40.
For ex: if your fourth digit is 4 and 5th is 9, that means 49>40...so new boot room 593.3.2. Old boot room version is 593.

So in short... the BIG solution that was promised would not help most of the 3Gs 3.1.3 5.12.01 baseband on the new bootroom and we are still left hanging with a 35k piece of tech brick!!! You can try but most likely you would just end up getting a 1600 series error code during restore!

Yep heard about that one too. Guess placing the antennae on the outside was not a good design choice after all!!
Other articles say that they are ruling it out as a software issue than a hardware problem.. so they would just release another patch update and get it fixed in the future OS releases! Typical Apple =)

Would these sim free phones in UK work in India with any GSM operator ? The iphone 4 should be in India by September or so, but dont know if they would continue to be tied to the previous Airtel/Vodafone providers.

Going by 600 GBP price in UK, we seriously need subsidy for this Rs 42k phone, if not higher. I was hoping that introduction of 3G would boost the sales of these phones, but with 3G auction ending so costly I am waiting to see what would be the pricing of the plans.
